Diagram XVIII. 



The isogamous Eremascus forms the beginning from which two 

 branches separate, an isogamous (with sprout cells) and a heterogamous 

 (with cell division) ; both end with chiefly parthenogenetic forms {Endo- 

 myces decipiens and E. capsularis). As the Saccharomycetaceae still 

 possess true sexuality they cannot result from these end forms but they 

 must branch off earlier, e.g., at the level of E. Magnusii and E. fibuliger. 



The family of the Saccharomycetaceae is divided into two lines, 

 according to whether the development of their sprout cells agrees with
